Abstract: A model for the description of particle emission after electro-excitation of a nucleus is developed. The coupling between the individual decay channels is treated within the framework of the continuum random-phase approximation. The interference terms between charge and current operators as well as the interference term between the two different transverse components of the current operator are included in the calculation. The model is applied to the proton decay of $^{16}$O and of $^{12}$C. The sensitivity of the angular distribution of the emitted particle to the presence of weak multipole strengths is analysed. Coincidence experiments are shown to be a selective tool to excite bound states embedded in the continuum. Quasi-free knock-out is found to start immediately above the giant dipole resonance region. The analysis of the $^{12}$C(e,e'p)$^{11}$B data of Stanford exhibits clear effects due to the presence of monopole strength, even though no concentrated monopole resonance is present in the theory.
